During an appearance on MSNBC's The Last Word with Lawrence O’Donnell on Thursday, Democratic U.S. Senate candidate Elizabeth Warren said she is in agreement with incumbent Sen. Scott Brown on pending insider trading legislation, but the agreements stopped there.

When O'Donnell asked Warren her opinion of the Brown co-authored STOCK Act, and it's ability to limit members of Congress from buying and selling stocks based on non-public information, she said she supports it, but would take legislation one step further.

"I think it's great to ban insider trading. What I'm asking though, is can't you just make it a little bit tougher?" Warren said. "I don't think members of Congress ought to own stock in companies that they're writing laws that can make a difference in their financial outcomes. What I'd like to do is tweak it up a little bit, but I'm really glad to see it."

"Either don't own it or put it in a blind trust where someone else manages it. I realize there's some wealthy individuals, I'm not one of them, who have a lot of stock portfolios," Warren said. "I don't understand how people can be out there in the House, in the Senate, and they get inside information and they're making critical decisions. We need to feel like they’re making those decisions on our behalf, not as an investor who would do better if the law goes this way instead of that way."

The second sentence in that statement, which is italicized for clarity, brought Warren some grief on Friday as the video clip circulated the Internet.

Critics charge that Warren was downplaying her own stock ownership, which is significant when considering individual stocks and mutual funds, according to her financial disclosure reports.

The financial disclosure report shows that Warren owns between $100,000 and $250,000 in individual IBM stock and between $2.8 million and $7.9 million in mutual funds.

Kyle Sullivan, a spokesman for the Warren campaign, told the Boston Globe that she was only referring to individual stocks sold for single companies.

“Elizabeth was making the point that unlike many members of Congress, she does not have a broad portfolio of stocks in individual companies," Sullivan said in the statement. “If elected she’ll get rid of the one stock she does own."

Later in the interview, Warren was asked about a statement Brown made a week ago, when he said that GOP Presidential hopeful W. Mitt Romney's wealth was in a category that most people, himself included, "can't understand." Warren acknowledged Romney's wealth and said the real inequity lies in his income tax rate.

"Mitt Romney pays 14 percent of his income in taxes and people who get out there and work for a living pay 25, 28, 30, 33 percent. I get it," Warren said. "Mitt Romney gets a better deal than any of the rest of us because he manages to earn his income in a way that's been specially protected for rich folks. I think that's wrong."

Warren also said that she would support closing tax loopholes which large corporations use to duck "paying their fair share" while giving tax breaks to small businesses.
